Overview
Code70 is an open-source printed circuit board by jhovannyLinares, from the jhovannyLinares/code70 repository on GitHub. It is a 2-layer board of 162.1 × 106.3 mm with 97 parts on 63 nets, routed with 1,904 tracks and 176 vias.
Its parts include 35 diodes, 35 switches, 5 connectors, 2 resistors and 1 IC. It belongs with the AVR (ATmega, ATtiny) boards of this library.
README
README.mdCode70
A 70-key split mechanical keyboard (35 keys per half), designed in KiCad and derived from Lily58 Pro.
Features
- Reversible PCB: the same board is used for both halves, selected with jumpers.
- 35 hot-swap sockets per half (Cherry MX / Kailh low profile footprint).
- Pro Micro controller (ATmega32U4).
- 4-pin I2C OLED display.
- TRRS cable between halves.
- SOD-123 diodes, reset button and M2 mounting holes.
Repository layout
| Folder | Contents |
|---|---|
pcb/ | KiCad 5 project (Code70.pro), schematic, board and Gerber files |
library/ | Footprints and the symbol cache used by the project |
case/ | Laser-cut template (plantilla-corte.ai, Adobe Illustrator) and board outline (SVG) |
layout/ | Key layout spreadsheet (Spanish layout, with ñ) |
Library paths are relative to the project (${KIPRJMOD}/../library), so pcb/Code70.pro opens without extra setup.
Fabrication
The Gerber files in pcb/gerber/ and pcb/Code70_gerber.zip were exported on 2021-02-12, and the board file was saved again on 2021-02-15. Before ordering, open pcb/Code70.kicad_pcb and export the Gerbers again so they match the latest board.
Firmware
Firmware is not included yet. QMK firmware for this board must define the Code70 matrix; the Sofle keymap does not match it as-is.

Questions
How big is the Code70 PCB?
It measures 162.1 × 106.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Code70 use?
97 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Code70 KiCad files?
From the jhovannyLinares/code70 repository on GitHub, at the commit this page was made from: the board is pcb/Code70.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Code70 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jhovannyLinares before reusing the design.
